Sagittaria aginashi
is a perennial herb occurring in marshes. It forms many small corms
in the leaf axils to make vegetative reproductions, not runners.
With pedicles and leaves radiating from roots directly, those blade
portions are arrowhead-shaped, i.e., elongated and triangular, and
have the two basal lobes prolonged downwards. Dorsal lobes are
longer than the other lateral ones. Leaf tips are not sharp,
regardless of lateral or dorsal ones. Long flower stems, 30-80cm in
height, set whorled racemes in which white 3-petaled flowers,
1.5-2cm in diameter, bloom. Bloom time: June-October. |
